title: What is the outcome for patients presenting with severe acute pancreatitis requiring a hospital stay of more than one month?
abstract: OBJECTIVE
  The aim of this study was to investigate the clinical progression of patients who had severe acute pancreatitis (AP) and a stay in hospital of more than a month.
  
  
  METHODS
  A total of 24 patients (median age: 57 years) were included in this eight-year retrospective study. Cure was defined as the restoration of the pancreatic parenchyma, and the disappearance of all pseudocysts and pancreatic fistulae. Data including the duration of hospital stay, disease severity and pancreatic sequelae were also collected.
  
  
  RESULTS
  The median total duration of the hospital stay was 67 days. The overall mortality rate was 20.8%, whereas the mortality rate due to AP was 12.5%. The average healing period was 7.7 months. On univariate analysis, patients who also had respiratory diseases, chronic alcoholism, necrotizing superinfection, pseudocyst, food intolerance and/or hospital-acquired infection took significantly longer to heal. After cure, we observed pancreatic and/or hepatic duct stenoses in 50% of cases, and the onset or aggravation of diabetes in 25%.
  
  
  CONCLUSIONS
  In patients hospitalized for more than one month because of necrotizing AP, the rate of mortality is around 20%, with a final hospital stay of two months and a healing period of more than seven months. In addition, half of the patients presented with pancreatic or biliary sequelae.
